This study will recruit women presenting for abortion or contraceptive services at the Columbia University and New York Presbyterian affiliated Family Planning Clinic and Special Gynecology Services who desire DMPA for contraception. Women will be randomized to two groups: self administration of SC DMPA or clinic administration of SC DMPA. The primary objective of this study is to compare the continuation rates of SC DMPA between the self and clinic administration groups at 6 months. Secondary outcomes include participant satisfaction, cost effectiveness of self-injected use of DMPA, baseline predictors of method continuation or discontinuation, evidence of persistent skin changes following administration of SC DMPA, and need for continued clinical support.
